Watch: Vin Diesel 'covers' Stay With Me

In a clip that should probably be given an xXx rating, Vin Diesel flexed his musical muscle in covering Sam Smith's 'Stay With Me'.

The Hollywood star, out on the promotional trail for Guardians of the Galaxy was, quite inexplicably, encouraged by Capital FM to have a crack off some karaoke. Reading the lyrics from a laptop screen, the results are...well, as Smith himself put it, surreal.

Vin diesel just covered Stay With Me. Surreal. Thanks man haha
